I play the keyboards professionally, there was a really good saying I came across (no idea where it came from):Kontarek said:I'd never heard this one before, but I have to say I LOVE the left-hand part of that piece. Awesome rhythm. I only started teaching myself piano around 2 years ago, but I completely empathize with the self-criticism as well. There's always those little lingering sections of a piece that I never feel like I can really nail as well as I'd like.
Ameteurs practice until they get it right; Professionals practice until they can't get it wrong.
Can't get any simpler than that really, it's all about practice, practice and more practice. Sometimes you practice it really slowly (tedious but it works!) You probably already know all of this though...
I've recently lost sight of that, my self-discipline waned after starting college and there was no piano tutor to push me the same way they did in secondary school. That video was made in my college years, and it was only recently I've decided I need to start playing more regularly and trying to push myself again.
You could always try a direct line-in to your computer although you'll need a sound card and/or interface that can handle it. Or if possible get a MIDI cable and DAW (I think are some free ones around), grab some piano sounds (there are free ones out there if the DAW doesn't come with any) and record the sound that way.And now I really wish I had videos to back up what I am saying/show off mah mad skillz. I don't know. I keep telling myself I'm going to do more videos, but it's difficult for me to get my hands on a camera and I don't really like the way the speakers on my digital piano sound... so... yeah...
I think I can record my piano pretty well now sound-wise, but in regards to video I have an iPhone as my camera...
